This message is an open letter to Republican voters in Ohio and Florida.

Dear Florida and Ohio Republicans,

We probably don't agree on much, but I have to say this or I'll regret it forever: You have a choice today. You can vote for Cruz, Kasich, or Rubio, and deny the nomination to Donald Trump, which will probably result in a brokered convention and quite possibly the most violent convention since the Democratic convention in Chicago in 1968. It may also result in the destruction of the GOP, at least in the near term, possibly in the long term.

Or, you can vote for Trump, and virtually hand him the Republican nomination on a platter. This will probably avoid a chaotic convention, but will probably also sound the death knell for American democracy if he's elected in November and is able to consolidate his power. That may sound overly dramatic. It isn't. I have no love for his GOP opponents, but they aren't demagogues. He is.

You can destroy the GOP, or you can destroy our country and what it has always stood for.
